Release Information
Statement introduced in Junos OS Release 10.0.
Description
Configure the method, if any, that the BSG uses to accelerate the process of DNS name resolution for SIP servers.
Options
initiate-alternative-queries—If this flag is on, the BSG initiates a name authority pointer (NAPTR) query, both a TCP and UDP service record (SRV) query, and an address record (A) query in parallel for each new SIP URI that it receives in a new transaction. This flag saves time if the NAPTR query fails.
Default: off
initiate-next-queries—If this flag is on, the BSG sends A record queries to all SIP servers returned in the SRV response instead of querying the first A record in the SRV response.
Default: off
no-refresh-before-ttl-expiry—if this flag is on, the BSG removes the SIP server from the cache when the TTL expires. If this flag is off, the BSG re-queries the A record and if the query is resolved, the BSG refreshes the TTL. As a result, the entry is not removed from the cache.
Default: off
Required Privilege Level
